摘要

叙述了对电力电容器噪声问题的研究及到目前为止所取得的进展

重点介绍了电容器噪声产生机理、测量方法（机械激励测电容器固有振动特性的方法及测量点距离声源比较远时的估算方法）、影响因素（包括极板层间间隙、浸渍剂、热处理、高次谐波、电容器容量）及应对措施方面研究的成果和存在的一些问题。

Abstract

In this paper

progress in study on capacitor audible noise at home and abroad is described.Some aspects are mainly introduced

such as: the mechanism

the measurement methods（hammer-excited method to get capacitor natural vibration characteristic and estimation method while the measuring point is far away from the source）

the influencing factors（space between the capacitor plates

impregnant

heat treatment

high frequency harmonics

and capacitor capacity）

the countermeasures as well as comments on the results and existing problems.
